Science and Astronomy Questions

What prevents us from perfectly modelling what these properties are?

Or, to turn the question upside down, by measuring these properties what new fundamental knowledge of physics do we get?

Science and Astronomy Questions

22843 The ISS is sort of a reference point, since they have serviced Hubble many times. All service missions to Hubble were with the space shuttles.  Hubble was designed with service missions by the shuttles in mind, which paid off, because when Hubble was taken to orbit, the mirror was found to be...

Science and Astronomy Questions

ISS orbits at ~405 km at an inclination of 51.6 degrees, Hubble at ~540km at 28.5 degrees.  You would need a very special mission to change Hubble's orbit to align with that of ISS.  And even if that's done, what good would an ISS rendezvous do to salvage it?  You would need a space shuttle to captu...

Astrophotography

22772 The plight of astronomers and astrophotographers everywhere It's a setup of four cameras, one will be replaced with a better one, and if my calculations are correct, the cameras will then combined cover the entire sky, effectively giving a 10 megapixel view of the sky recording up to 30 fps. ...

I think for alliteration to work, it must be on the stressed syllable.  So alliteration works well for Germanic languages which generally stress the first syllable (but English has warped quite a bit).  I don't see modern authors use that much, though.  Tolkien may have used it to some degree modell...

If you think of adding poetic devices, remember alliteration, which for some reason is often forgotten these days.  For instance, wouldn't the last sentence sound so much better as "swallowed by the surging storm"?

Some nice aurora on northern Norway tonight.  Here's a clip from one of the cameras in our meteor network:

The Future of Humanity & Intelligent life in the universe

There's one possible problem to interstellar travel.  Dust.  Interstellar dust is extremely sparse, but given the distances and the great travel speeds, could it pose a problem?  Has anyone tried to calculate the risks?  A small pebble, even just a gramme, will utterly destroy your spacecraft hits i...

22565 I always find it interesting how the vegetation changes as you go up in altitude I also find it interesting how vegetation changes with time.  If I had a time machine and went back in time, I would experience striking changes in the forests surrounding Oslo.  Going back 100 or 200 years, if w...

Looks like a nice area for hikes.  Interesting to see how pines mark the upper limit for trees.  In Scandinavia there is a zone where dwarf birches take over where pines have to give up.

Yes, the double rings hint that.  But I actually liked the idea (perpetual day except for eclipses).

Simulation Hypothesis Topic

22406 Making assumptions about how the "true universe" leaks into our simulated one is not in itself a problem. This seems to me as a general problem even in current science.  We can't know whether what we perceive as reality is just an emergent feature from a reality which is fundamental...

Simulation Hypothesis Topic

If living in a simulated universe, we know nothing of the physics of the real world, and simulating our reality in that real universe could be quite plausible.  But without hints of the "real" world leaking into our world, all simulated world arguments are pointless.
